Single target acuity (STA) is a key measure for understanding visual object perception in harbor seals. While STA was already determined with stationary and moving compact single targets of different contrasts in air, we herein assessed und...
Changing 3D heading direction in terrestrial locomotion: effectiveness of visual landmarks and the onset of turning in stick insects [0.03%]
步行stick insect改变行走方向时视觉路标的作用及转向的开始阶段

Climbing animals need to be able to adjust their heading in both vertical and horizontal directions, requiring pitch and yaw rotation of the body axis, respectively. Stick insects are climbing herbivores that dwell among leaves and branches...
Beamforming as a mechanism for azimuthal localization of targets by FM-echolocating big brown bats [0.03%]
调频回声定位的大棕蝙蝠的方位目标定位机制——波束形成的作用

James A Simmons
Echolocating big brown bats broadcast downward-sweeping, frequency-modulated (FM) biosonar sounds and process the returning echoes to track and capture flying insects. Neurons in the inferior colliculus are tuned to different frequencies al...
Photoperiodic control of the albumen gland by neurosecretory canopy cells in the pond snail Lymnaea stagnalis [0.03%]

The pond snail Lymnaea stagnalis displays clear photoperiodism; it lays more eggs in long-day conditions than in short to medium-day conditions. The lateral lobes (LLs) are paired small budding structures of the cerebral ganglia and regulat...

Communication systems shape behavioral interactions that are crucial for recognition, territoriality, and reproduction across animals. In many anuran species, acoustic communication drives reproductive and defensive behaviors as males produ...
Looking ahead: echolocation and flight behaviors of two fruit bat species navigating a corridor [0.03%]
展望:两种果蝠种利用声呐和飞行行为穿越一条林隙的行为学研究

Bats navigating clutter must steer around obstacles to avoid collision, while simultaneously planning future flight trajectories. In this study, we investigated active sensing strategies of two bat species negotiating turns under matched ge...
Bioamine disruption leads to memory deficits in the whip spider, Phrynus marginemaculatus [0.03%]
扰乱生物胺的合成会导致斑节拟步甲记忆缺陷

Amblypygi (whip spiders) are an order of arthropods (Subphylum: Chelicerata, Class: Arachnida) that navigate primarily by their keen olfactory abilities. Experiments in the laboratory reveal that the species Phrynus marginemaculatus forms b...

The brain regions supporting spatial navigation are well studied in mammals, but their function in the spatial behavior of other vertebrates is poorly understood, especially in field conditions. Here, we measured the behavior and neural cor...
Otolithic organs and vibratory sensitivity in frogs: do saccular otoconial volumes vary according to lifestyle? [0.03%]
蛙类前庭感觉器官的耳石大小与生活习性之间的关系研究
Matthew J Mason,Sandra Goutte,Piers J Seal et al.
Matthew J Mason et al.
Of the three otolithic organs found in frogs, the sacculus is known to possess acute sensitivity to seismic vibrations. Simple models of otolith function suggest that increasing size of an otolith should improve vibratory sensitivity. In th...
